Daniel, I'm not vegan so I really didn't notice if those options were included on the menu, however for the price paid for a dinner for two (substantial) I believe you should be able to obtain vegan meals. Call in advance to confirm or ask them directly, with all the dining options available today, they will likely do what they can to accommodate you.
Yes, they do!
Last time I was there I believe they offered a complete vegan tasting menu. They will certainly try to accommodate special requests.
The staff are very accommodating when it comes to dietary restrictions. Be sure you alert the staff of what you need and they'll tell the chef.
